BALL-RETAINER FOR THRUST-BEARINGS.

Specification of Letters Patent.

Patented Feb. 1, 1916.-

Application filed August 14, 1914. Serial No. 856,749.

To all whom it may concern:

Be it known that I, CARL AUGUs'r THEO- DOR SfjRENsEN, a citizen of the Kingdom of Sweden, residing at Gottenborg, Sweden, have invented new and useful Improvements in Ball-Retainers for Thrust-Bearings, of which the following is a specification.

This invention relates to ball retainers for thrust ball bearings of the kind which con-.

against the part of the ball retainer keep-- ing the balls apart resulting in wear and tear as well as seizing of the parts.

This invention has for its object to prevent the said drawbacks chiefly, in this that both main parts of the ball retainer are kept centered in relation to each other by means of rolling members such as balls or rollers placed between said parts, so as to prevent lateral displacement of the parts of the ball-retainer relatively to each other but at the same time permit one of said parts to rotate in relation to the.

other with slight friction.

I attain these objects and advantages by means of the construction shown in the ac- -companying drawings in which and consists,

the balls is rotatable relatively to the plates a and b. Placed between the'ring f and the plates av and b are two series of balls 9 and h by means of which the parts of the ball retainers are kept well centered relatively to each other, While at the same time said parts may rotate in relation to each other with slight friction. The points of engagement of the balls 9 and h are suitably located on each of two cones coaxial with the axis of the bearing, so that said balls are capable of sustaining axial as well as radial thrusts.

f but may, if desired, be placed at the outer side of said ring, as is shown in Fig. 2, or at the upper and lower sides thereof, as is shown in Fig. 3.

By the arrangement described above the advantage is obtained that the balls (Z in outward direction bear against the member f only and, consequently, at a single point (the pole of rotation). "The balls d'bear, it

is true, against the member a in points lying on a circle, the center of which is located on the axis of the bearing, but the pressure in these points is considerably smaller than in the outward direction (2'. e. in the direction of the centrifugal force) and on account thereof no friction detrimental to the bearing can arise at said points of engagement;

Having thus fully described my inven tion, what I claim is 1. A ball retainer for thrust ball bearings, consisting of two parts rotatably mounted in relation to each other, and rolling members between said partsvfor centeringthem in relation to each other.

2. A ball retainer for thrust ball bearings, consisting of two parts rotatably mounted in relation to each other, one of said parts forming a separator for the bearing balls and the other forming a support for said balls in radial direction, and rolling members centering said parts in relation toeach other.

3. A ball retainer for thrust ball bearings,

The balls 9 and it need not necessarlly be placed at the inner side of the ring consisting of a ring-shaped part encircling In testimony whereof I have hereunto the bearlng balls, a ball retzunlng and sep set my hand 1n presence of two subscrlblng aretlng part and balls between stud parts wltnesses.
